The invention relatesto a device for asoer taining the quantitative'ratio of the comingthe lengths of the particles.

Devices of this kindhave been in "use for the geometrical analysis of rocks and, opera ate by moving the specimen which :is to be analyzed under an optically fixedpointyan-d then measuring the length of'the. motions of certain individual components vi dual measurements are-added and reduced to percentage values; 'The movement and measurement of the mineral is eflfected means of two slides operated by screws and 1 tudin'al guldes 6- and 7 in the form of-up moving ithin each otherj fand Qmounted Withinan outer stationary frame. .The cut;

ground and polishedfspecimen is aflined to the inner slide and the whole apparatus mounted upon the, stage of amicroscope.

The measurement having been completed 7 with respect toIa certain componentgsay quartz in granite; along any I given line, the

apparatus is screwediback. vIt is then displaced transversely by a screw or other suitable means; after which the measurement is repeated. along a fresh line. In theseknown V devices'it is not practicable to measurefdit.

ferently, constituted components in one 'operation. They are restricted to measuring one particular"v component, and the whole process must be repeated for every other com-' ponent. This involves the further disadvam tage that the values resulting from measurements along any individual vgauge line re quire to be writtendown for subsequentadditionat the endoflthe wholeiprocess,

The invention here described eliminates these; disadvantages an arrangement J whereby each component has a separatemovement and means ofmeasuring it',:and whereby the final resultof all'measured lines is indicated'at the conclusion :of the operation;

ig. 3 is a'crosssec tion of one ofthe mea s- [.urlngf'devices;

The device consists of a; circularbase li for attachment 1 to an instrument "such as a;

guides 30, 31between which is slidablyg mounted a transverse slide 2 operable bya "screw 35 having a knob 42' inengageme'n H, with a rackj36 on the slide. The latter hasf a scale 37 which cojoperates 'withavernier 318 Q on one of the guides tov indicate the-magma tude of the movement of the slide. i v

The slide '52 carries a base 5 havinglpngi: 1 a

standing flanges; o 3 and 4 are guides forfthe o I longitudinal slide 1 to whichis secured'an-j; V

abutment 19 having a straight edge 25. The

slide 1 is movable longitudinally by means; to be presently described against the tension of slide returningsprings 33, 34 which oper- 1.

The slide .1 is moved against thelspriiigsj byv means of wedges,inthis case siX',numbered,, *7 K to Kfinclusive I The wedgesare capable;

of moving longitudinally to shift the slide being placedbetween the latter and a for ward fixed stop 2i havinga straight edge 22 and secured to the base 5 byiscrews23;

'sists "of a fixed sleeve 18 which is secured to The nose projects beyond the sleeve and U l outsidethe latter the nose engages a notch 14;: i i in a scale tube 15 which surrounds thesleeve I the adjacent flange6 or 7 and forms a hearing If v-f or= the measuring device. Inside the sleeve 1 '18 there is a tubularnut '10 provided with a;

nose l1 whichslides in aslot 12 inthesleevef 18.: Thus the scale tube 15 andtheinut lfi operate together as one element. The tube 15 ed to move in overthe tube 15. The screws may be clamped to 18 by a screw. The clamping screws are marked 1 to 1 inclusive.

From this. it willbe seen'that when the screwl is clamped down on sleeve 18, the

scale tube 15 and'the nut 10 cannot move being enga'ged with'each other at 11-14. Conversely, when the screw 1 is loosened, the scale tube'15 and the nut are together free to slide with respect to. the sleeve 18 but can;

not rotate because of the ,no-se11 which can only slide in the slot 12 in the sleeve 18, but

cannot rotate in the latter when the screw 1 is loosened. 9 indicates a tubular graduated head whicl is secured to an operating screw 8 in engagement with the nut 10. A scale '17 on thehead 9 cooperates vwith another scale 16 on the tube 15. The head 9 is adapt 8 are in the same horizontal plane as the corresponding we'dgesli tol K, whichfare covered by a plate 41, Figure 3.

" YWhen the clamping screws, 1 1 are loosened, j the screws 8 are kept in contact with their respective wedges by means of a spring f located within a tube 27' and secured to a' sleeve 28; The latter carries a collar 29 1 in engagement with the collar 26 on the scale a tube which also serves as a bearing for the clamping screw. When therefore'all' clamp ing screws are loosened and the springs 333tpush the slide 1 and the wedges back into initial'positions, the. screws 8 remain in touch with the wedges.

The deviceis attached to thestage of a microscope so that its longitudinal aXis'is parallel with the vertical thread in the objective, "all scales are set at Zero and the screws 1 -1 screwed down. The specimen is under the microscope by meansof measuring device m for instance. This is done by rotating tubular ;;head 9 whereby the screw 8 is .movedinwardly against its wedge K Due .to the angular formation; wedges K 'K willmove/longitudinally a certain distance;

and initurn move the slide 1 against the springs 3334. The specimen-having been located, the measuring dev ce m 18. used to measure the first component part; The movement is observed in the microscope and shown on the fixed andmovab'lejscales 16and' 17..

Thereafter device an? is operated for the sec- 0nd component, and finally m is operated. Each time a measuring device is operated, the slide l with the specimen is moved and the distance registered on the scales. For such partsof the specimen which are not'to be measured, the specimen'is moved by-"m or for instance. 'These'measurements "may a distance until a component appears.

have been made along a single line, but if necessary, the entire measuring apparatus may be shifted transversely on slide 2' in order to measure along anotherlongitudinal. For exact results it is better to make the transversef moveinents as small as possible.

From theforegoing it will be clear that i by continuous operationof the three measuring devices, the totals of each .ofthe three sets of measurements will be shown on the scales 16 and 17 and then written down for I report.

When the operation is finished, thescrews 1 etc. are loosened and the springs 33 3 will then push the slide 1 and the wedges for ward into initial position. The scales 17 however will still show the measurements.

Thereafter the screws 1? etc. are again he tened and the scalesset at zero for another operation.

' f If there are portions on the specimenwhich are not to be measured, then a certain mea s-Y uring device is selected to move the specimen measuringthe'reof may then be resumed.
